Tier 5 (WoW)

Tier 5 refers to the set of class equipment that is acquired from the bosses of Serpentshrine Cavern and Tempest Keep, also known as The Eye. These sets are meant as a follow-up to the Tier 4 equipment found in earlier zones, but require a full (BC-era) raid of 25 to acquire. The sets are very similar overall to the Tier 4, and are not considered a massive upgrade so much as merely a step up.

Tier 5 can also refer to guilds working on the bosses in Serpentshrine Cavern (SSC) and Tempest Keep (TK), but have not defeated the bosses of those dungeons and moved on to Tier 6 content.
